Description

Cosmetic composition containing at least one branched sulfonic acid polyester and at least one conditioning agent {COSMETIC COMPOSITION COMPRISING AT LEAST ONE BRANCHED SULPHONIC POLYESTER AND AT LEAST ONE CONDITIONING AGENT}

The present invention relates to a cosmetic composition for keratinous fibers, such as hair, comprising at least one branched sulfonic acid polyester and at least one selected from the group consisting of nonvolatile silicones, cationic or amphoteric polymers and cationic or amphoteric surfactants. Contains conditioning agents. The present invention also provides a method of treating keratin fibers, such as hair, in particular a method of fixing and / or maintaining a hairstyle using said composition, as well as the use of said composition for or in the manufacture of cosmetic hair styling formulations. It is about.

For the purposes of the present invention, the term "keratin fibers" means hair, eyelashes and eyebrows.

The fixation of the hairstyle is an important element of the styling, which consists in maintaining the already made shape or shaping the hair and simultaneously fixing it.

The most widely marketed hairdressing and / or maintenance hair products on the cosmetic market have essentially the ability to form a bond between hair as a mixture with a solution, usually an alcoholic or aqueous solution, and various cosmetic aids. One or more substances, also known as substances, generally are spray compositions composed of polymeric resins. These solutions are usually packaged in a suitable aerosol container, or pump dispenser bottle, placed under pressure with the aid of a propellant.

Styling gels or mousses are also known which are usually applied to wet hair before touching or setting the hair with a dryer. These compositions have the disadvantage that, unlike conventional aerosol lacquers, they do not allow the hair to be fixed in an already made shape. This is because these compositions are inherently aqueous and, when applied, do not allow them to wet the hair to maintain the shape of the initial hairstyle. Therefore, in order to shape and fix the hairstyle, there is a need to later touch or dry the hair with a dryer.

Most compositions in the prior art have the same disadvantage that users cannot easily restylize the hair to restore the hair to its initial shape when the hairstyle is forcibly released. In this case, it is often necessary to restart all the styling and fixation steps if you want to get your initial hairstyle back.

Therefore, there is a need for a styling composition that can easily recover its shape when the hairstyle is released by, for example, a strong wind or strong shaking. This ability is referred to as the "restyling" power, that is, when such a hairstyle is released, the possibility of easily reshaping the hairstyle with minimal effort, without using a comb or brush.

Another disadvantage of the prior art compositions is that they are not always able to properly care for all the hair, i.e. not all the hair can have the same shape and the same orientation. This sometimes gives the impression that the hairstyle is disordered and looks unmanaged. Therefore, there is a need for compositions that exhibit a manageable effect such that the head of the hair is sufficient to have a well-maintained shape.

Finally, the composition for fixing the hairstyle has the disadvantage of impairing the cosmetic properties of the hair. Therefore, the hair becomes rough, hard to loosen, loses a good feeling and shape, and the body can be lost. There is a need for a styling composition that imparts good cosmetic properties, particularly entanglement, softness, feel and body. For the purposes of the present invention, the head of the hair is considered to have a "body" if rich and slight strength is felt when touched by hand.

Therefore, there is a need to find cosmetic compositions, in particular cosmetic compositions for styling that do not have all of the above disadvantages.

Applicants have found that when mixing surprisingly and unexpectedly branched sulfonic acid polyesters with conditioning agents, cosmetic compositions that meet the above requirements can be obtained.

Accordingly, the subject matter of the present invention contains one or more branched sulfonic acid polyesters in a cosmetically acceptable medium and one or more conditioning agents selected from the group consisting of nonvolatile silicones, cationic or amphoteric polymers and cationic or amphoteric surfactants.
